If you include your own email addresses or aliases in your Address Book, you're Whitelisting that address - and all the spam that forges your own email address into the From field will make it into your inbox. The vast majority of spam is sent with fake From addresses and in many cases the From address of the spam will be the same as the To address. Tip! Do not list any of your own email addresses or email aliases in your Address Book. You can even import your Outlook, Eudora, and Netscape Mail address books making it simple and easy to safeguard all of your most important addresses in one easy step! Never again worry about your most important email being accidentally filtered. Add an address to your CCC Address Book and all email from that address will always be delivered to your Inbox. Your email is important! Even the best filtering methods can sometimes make mistakes, which is why Avvanta provides an easy method to protect the email sent to you from your friends, family, and business associates.
Use the filters to stop persistent spammers, protect email from important sources, or to organize your email automatically. Take control of your email! Avvanta provides you the ability to fully customize your email rules with filters you define. You choose how many points are needed as your Spam Threshold. Spam Assassin instead assigns a point value to each rule the message matches, and the more points a message accumulates the higher the probability is that the message is spam. Since many of these characteristics may appear in legitimate email Spam Assassin doesn't automatically assume that a message is spam if any single rule matches. Fake email addresses, fake headers, garbage text and of course the language commonly used in junk email like the infamous "make money fast".
Spam Assassin examines an email looking for characteristics common to all spam. The venerable Spam Assassin ® Rules Based Filtering system.

Every email arriving on the system that makes it past the DNSBLs must then pass through AvvantaAV's rigorous anti-virus scanner.
Avvanta's Anti-VirusĪvvantaAV service (powered by ClamAV) is automatically enabled for all Avvanta mailboxes. (1 day, 2 days, 4 days, 8 days etc.) Using this sliding scale method SPIKE has become extremely effective at curtailing the amount of junk mail received from dedicated spam operations while minimizing risks to legitimate email senders. If that IP address starts spamming again in the future it takes fewer spams to be re-listed and the time spent in the SPIKE list is doubled each time. Once enough spam has been received from a single source SPIKE automatically blackholes that IP address for a minimum of 24 hours after which it is automatically de-listed. Should an Avvanta subscriber's filter tag an email as spam the IP address of that spammer is already known and a score gets attached to that spammer's IP address. SPIKE monitors all incoming email and monitors where that email came from. S.P.I.K.E.Īvvanta's own highly sophisticated realtime Blackhole list.
